boring

BoringSSL is Google's fork of OpenSSL for Chrome/Chromium and Android.

This crate provides safe bindings for the Rust programming language and TLS adapters for tokio and hyper built on top of it.

It supports FIPS-compatible builds of BoringSSL, as well as Post-Quantum crypto and Raw Public Key extensions.

Upgrading from boring v4

• First update to boring 4.21 and ensure it builds without any deprecation warnings.
• pq-experimental Cargo feature is no longer needed. Post-quantum crypto is enabled by default.
• fips-precompiled Cargo feature has been merged into fips. Set BORING_BSSL_FIPS_PATH env var to use a precompiled library.
• fips-compat Cargo feature has been renamed to legacy-compat-deprecated (4cb7e260a8)
• SslCurve and SslCurveNid have been removed. Curve names are more stable and portable identifiers. Use curve_name() and set_curves_list().
• Ssl::new_from_ref -> Ssl::new().
• X509Builder::append_extension2 -> X509Builder::append_extension.
• X509Store is now cheaply cloneable, but immutable. SslContextBuilder.cert_store_mut() can't be used after .set_cert_store(). If you need .cert_store_mut(), either don't overwrite the default store, or use .set_cert_store_builder().
• X509StoreBuilder::add_cert takes a reference.
• hyper 0.x support has been removed. Use hyper 1.x.
